Re: Why Does GPS work fine one day and not the next?
FYI, GPS on the Vogue is mostly NOT A-GPS... In fact, I can't say I've ever seen A-GPS ever work... It works (for free,) off of the US Military's GPS satellites.
Sprint cannot block true GPS, and I don't believe they try to block A-GPS either...
The reason the GPS works one day, and not the next, has to do with stand-by mode. I have noticed, if I use a program that utilizes GPS many times a day, like GPSToday, then I lose GPS ability after a few hours. It has to do with the GPS driver and standby... If I disable the automatic feature of GPSToday, then, I can use GPS almost indefinitely without a problem. I determined that 99% of the time, GPSToday doesn't really provide useful information on the Today screen, but the geotagging software is fairly useful. I turned off the automatic update on GPSToday, and turned on geotagging. When I take a picture, THEN it connects to the GPS. If I wait for GPS to connect, tag the picture, and wait for the GPS to disconnect before turning off my phone, I have no problems.
Before, with automatic update, GPS would turn on simply from getting a text message. Many times, my phone would turn itself off before it got a lock, causing the GPS driver to eventually freak out... Heck, maybe it kills the driver if it encounters too many unsuccessful lock? Who knows... but it sure isn't Sprint...
